SPECIFICATION formingpart of Letters Patent No. 699,516, dated May 6, 1902. Application filed February 5,1902. Serial No. 92,625. (No model.)

To all whom it ntcty concern:

Be it known that I, JULIUs HACKENBERG, a citizen of the United States, residing in Hoboken, county of Hudson, and State of New Jersey, have invented certain new and useful Improvements in the Manufacture of Celluloid Articles, of which the following is a specification.

This invention relates to certain improvements in the manufacture of celluloid articles such as combs, napkin-rings, and the likeso that the exterior appearance of the same is greatly improved and a more ornamental and attractive appearance imparted to celluloid articles made in imitation of tortoise-shell; and the invention consists, first, in a process of making ornamental celluloid articles by forming blocks or plates composed of differently-colored strips of celluloid arranged according to the designs desired to be produced, cutting small pieces transversely from said blocks or plates, cementing them together into strips or bands, then cementing them to the body of the article to be ornamented, and finally molding the so-ornainented article into proper shape by heat; and the invention consists, secondly, of an ornamented celluloid article the body of which is provided with designs formed of strips or bands of individual diiferently-oolored pieces of celluloid cemented together and to the body of the article to be ornamented, as will be fully described hereinafter and'finally pointed out in the claims.

In the accompanying drawings, Figure l is a front elevation ofa celluloid hair-comb ornamented according to my invention. Fig. 2 is a plate formed of a number of differentlycolored strips of celluloid cemented together. Fig. 3 is a strip cuttransversely from said plate at right angles thereto. Fig. 4 represents similar strips cut at an oblique angle from said plate. Figs. 5 and 6 are narrow separating-pieces of celluloid that are interposed between said strips and cemented to the same. Fig. '7 is a perspective view of a rectangular block of celluloid formed of differently-colored longitudinal pieces. Fig. 8

represents small pieces of celluloid cut transversely from said block. Fig. 9 is an end view of one of the separating-strips of celluloid which are interposed between the so-ornamented pieces cut from the block and cemented to the same, and Fig. 10 is an ornamental band or strip formed of the square pieces and separatingstrips cemented together for use in ornament-ing the celluloid articles.

Similar letters of reference indicate corre sponding parts.

In carrying out my improved manufacture of celluloid articles anumber of longitudinal strips a of differently-colored celluloid of different widths are cut from the plates of celluloid of uniform thickness and then cemented together at their sides by means of the wellknown celluloid-cement at ordinary temperature, so as to form either plates B or blocks 0, as shown in Figs. 2 and -'7. From the plate B narrow strips D are cut at right angles to the body or obliquely thereto on the dotted lines in Fig. 2, so that ornamental strips or bands D are obtained, as shown in Figs. 3 and 4C. These strips or bands D are connected with each other by cementing together either directly or by interposing the narrow separating-strips e, as shown in Figs. 5 and 6, between them or by arranging them in zigzag or other relative position toward each other, as shown in Fig. 1. When the blocks 0 are cut into thin plates or pieces transversely to their longitudinal axes, the individual pieces or plates f have the same geometrical ornamentation that is formed by the arrangement of the strips forming the block, the plates or pieces being cemented together directly or withintermediate separatingpieces f, so as to form the continuous band or strips F. (Shown in Fig. 10.) By suitably grouping and cementing together strips or bands cut from the plate 13 and block 0 any desired geometrical design of a mosaic appearance is obtained. These difierent strips or bands are then cemented together and to the blank of the body to be ornamentedin the case of a comb at the headpiece and of a napkin-ring at the edge of the same. The thus-ornamented celluloid blank for combs, napkin-rings, &c., is then heated and molded into the shape required for use.

B y the process described the different articles of celluloid which heretofore were made only in imitation of'tortoise-shell can be ornamented in a great variety of geometrical and other designs, and thereby their appearance greatly improved.

Having thus described my invention, I

- claim as new and desire to secure by Letters Patent 1. The process herein described of ornameniing celluloid articles which consists in making strips or hands of celluloid, formed of differently-colored .pieces of celluloid cemented together, and to the articles to be ornamented, substantially as set forth.

2. The process herein described of ornamenting celluloid articles, which consists of cementing longitudinal strips of celluloid of different colors into plates or blocks, cutting transversely from said plates or blocks narrow strips or plates, cementing said narrow strips or plates together into a suitable de-
